Hello. I am work with gnuradio 3.10 . I need a WCDMA receiver, but I can’t find it on GitHub. Could you help me please 1 post - 1 participant Read full topic ..read more

I am trying to send audio signal at 2 different channels(96 MHz and 99 MHz) using sdr but not able to transmit at two different channels at same time. Anyone knows how to use two TX channels in gnu radio? please in details thanks 1 post - 1 participant Read full topic ..read more

I have 3 signals example 100MHz 300MHz and 500MHz. I want to read and record these 3 signals, provided that the signals and gaps are 1 second. How can I do that ? I used the delay diagram, but there was no delay as I wanted. 1 post - 1 participant Read full topic ..read more

I want to ask how to use bt-100 power amplifier with bladeRF? cause when i try to enable it is enabling but not working for transmission of signal and in GRC when i run the flowgraph i get error like No devices available(-7). 1 post - 1 participant Read full topic ..read more

hi, i am at learning stage in gnu radio. And i want to check how much strong noise can be produce using bladerf 2.0 micro xA9 hardware with GNU radio companion? do i need to use power amplifier to produce strong noise? 1 post - 1 participant Read full topic ..read more

I record an 8PSK signal using the following scheme (1): After that, I open the recorded signals in Matlab and add them (signal = re + 1i*Im): After that, I demodulate.The original signal differs from the demodulated one. For demod i use comm.PSKDemodulator (8, ‘BitOutput’,true) If I decode the signal in GNU radio, then the signals are the same. Can you explain what the problem is and correct me? 1 post - 1 participant Read full topic ..read more

Hi everyone, this is my first post here. My goal is to read data held in binary file, decode them and stream to block’s output. Data are just sequence of floats. Moreover I also have a sampling rate, at which they were collected (it is constant for all data). I have C++ OOT module, based on source, I managed to decode file and now I have a vector of floats. How to put them to the block’s output as a stream of floats? int reader_impl::work(int noutput_items, gr_vector_const_void_star& input_items, gr_vector_void_star& output ..read more

Hi guys, Im 19 and trying to get into the world of sdr ( in college) so I set a target to myself: Create fully functional wireless FSK immediate message system with 2 usrp’s (using gnuradio). Has anyone ever done this before? Thanks❤ 1 post - 1 participant Read full topic ..read more

I’m trying to replicate a GNSS (Galileo) signal, I have the PRN code which is a 1.023 mega bit per second, and a navigation message which is a 50 bps. How can I force the Vector Source block to the frequency that I want, the frequency seems to be very high! a peak to peak is like 0.4 ms. 1 post - 1 participant Read full topic ..read more
